While I don't know for certain, of course, there has been a trend in the past few years of shows not selling the first few rows when tickets first go on sale. I would imagine it is to wait and see if the design of the show dictates needing those rows for set/orchestra purposes. As someone who prefers front row seats it is quite maddening to buy tickets early only to have rows added in later in front of the seats I've bought. So, I've started waiting.
